Research On Vibration Analysis And Diagnosis Methods Of Cementy Mechanical Equipment

Fault diagnosis on use of the vibration signals of machines in operation process is the most effective, most commonly used methods.The rotating machinery fault is complicated in industrial spots.Because of non-stationary signal, failure cause diversity,uncertainly between symptom and fault,fault hybridism, fault do not correspond to the symptom exactly.Actually engaged in equipment vibration analysis of the diagnosis, we should fully grasp the information of all kinds of equipment,and flexible use vibration principle and measurement techniques , and integration experience and professional knowledge.In this paper, the vibration signal diagnosis problems was Analysed based on vibration diagnosis theory. Spot diagnosis techniques was summarized about local unbalance,coupling damage,pedestal looseness concluded with case analysis. In practical work,we should attaches great importance to the development and change of the vibration process.The variety of vibration was an important fault symptom,for example,sudden accretion,increase and then decrease,and these indicated fault growing. regularly monitor is obligatory.Vibration acceleration is a important parameter in rolling bear diagnosis.Although the diagnosis of rolling bearings standard to vibration velocity as the basis, the vibration acceleration was a important parameter on the diagnosis of rolling bearing still.
